The vertical shaft kiln (VSK), or vertical kiln, is a kind of industrial equipment used to calcinate cement clinker. It is often used in small and medium-sized cement plants for cement production. With the continuous development of cement production technology, the shaft kiln in many regions of the world has been replaced by the rotary kiln, a more advanced cement clinker calcination equipment. However, in the vast underdeveloped areas, the shaft kiln is still an important equipment for producing cement because of its low price and simple design.
There are three VSK systems available:
1. Traditional VSK: Clinker output capacity from 60TPD to 400TPD
2. Patented AC VSK: Clinker output capacity from 500TPD to 1000TPD
3. Patented Differential VSK: Clinker output capacity from 700-1500TPD
After years of research and improvement on cement shaft kilns by our technical research and development team, we have developed two new types of shaft kilns on the basis of the traditional mechanical shaft kilns and successfully applied for national patents for them. We named these two kinds of shaft kilns AC VSK and differential discharge VSK respectively.
These two new shaft kilns have their own characteristics. Compared with traditional shaft kilns, their output and energy utilization ratio are greatly improved. According to customers’ specific needs and production conditions, we can customize the optimal shaft kiln scheme for them.
